if twenty five percent were the right answer, then you would have a fifty percent chance of guessing the correct answer, but that would make the correct answer 50%, and only one of the answers is fifty percent, which would therefore make the correct answer 25% but there are two answers stating 25% which would mean you have a 50% chance of getting it right if the answer were twenty five percent.

but, if the answer was 0% then you would have a 25% chance of picking the right answer, making the answer b) 50% because there are two twenty five % answers. and if the answer were 33% you would have a 0% chance of picking the right answer, making the coreect answer c), which would in turn give you a twenty five percent chance of picking the right answer, making the answer b) 50%.

If the answer is zero percent, then it's wrong. You can't have no chance of getting it right out of four. It's impossible. Making it 33%. But two answers are the same. 50%. BUT there is some sort of equation that I don't know at the moment that takes in consideration of various factors.

I don't want to put it in terms like this, but I'm going to because I lack a better example. Flip a coin fifty times, basic probability says 25% of the time, it will come up heads. However, this does not always happen. (I don't want to use this example because that's more of a chance thing whereas this is a fixed answer... But it's the best I have at the moment.)

Has anyone seen the movie 21? Where he's in class and is asked to choose between three doors, two have a prize and one has a goat, what are his chances of getting what he wants? This is a SIMILAR situation.

I'm saying the question is void because it does not have the correct answer.

ding ding ding, Its a paradox. No matter what the answer is, the fact that it is the answer makes the answer wrong, you cannot ever pick a correct answer, however, the correct answer cannot be 0% probability, because that answer also is wrong, no mathematical equation can ever give you the answer, because of the way the question is worded.
